PHP programs run automatically, Windows schedule tasks

Specifically, if we need to run the Task Scheduler automatically, we should perform the following steps:

1. Click the Start button, and then select programs → attachments → system tools → task scheduler (or settings → control Panel → Task Scheduler) to start the Task Scheduler management program for Windows 2000.

2. In the Scheduled Task window, double-click the Add Task Schedule icon, start the Task Scheduler Wizard for the system, click Next, select the application that you want to run automatically in the list of programs that you give, and then click Next.

3. Set the appropriate task schedule name and select the frequency of time to automate this task, such as Daily, weekly, monthly, one-time, every time you start your computer, and so on, and then click the Next button. At this point, the system will require the user to the program to run the specific time to set, such as the number, the clock, which time to run, and so on, we just need to set according to their own needs.

4. The system will then require the user to set the appropriate username and password (as shown in Figure 5) so that the system can be run automatically in the future.

5. Finally, we simply click the Finish button to add the task to the Windows 2000 Task Scheduler, and thereafter it automatically "remembers" the task, which automatically invokes the user-specified application once the system time and related conditions match the user-set schedule ( Each time you start Windows 2000, the Task Scheduler starts automatically and runs in the background to ensure that the user's schedule is executed on time.

Now let's test whether the task we just built was successful, right-click the "PHP" program icon (as shown in Figure 6), and select "Run" in the pop-up menu. In general, the program icon as long as the activation of the operation can start normally. If the run failed to see if the user and password are set correctly, and to determine whether the "Task Scheduler" service has been started, I was in order to save the system resources to turn it off, causing the operation failed, I found a long day. In addition, you can also see from the system log what causes the run to fail.

Okay, so much for the application of the mission plan, now that we cut to the chase, here are two examples:

First, let PHP run regularly

Edit the following code and save it as test.php:

$fp = @fopen ("Test.txt", "A +");
Fwrite ($fp, Date ("Y-m-d h:i:s"). "Let PHP run at regular intervals!" /n ");
Fclose ($FP);
?>

Add a task schedule and enter the command in this step (shown in Figure 2):

D:/php4/php.exe-q d:/php4/test.php

The time is set to run every 1 minutes, and then run this task. Now let's see if the contents of the D:/php4/test.txt file are successful. If the content is as follows, congratulations on your success.

2007-10-30 11:08:01 let PHP run regularly!
2007-10-3011:09:02 let PHP run regularly!
2007-10-30 11:10:01 let PHP run regularly!
2007-10-30 11:11:02 let PHP run regularly!

Second, let MySQL implement automatic backup

Edit the following code and save it as backup.php, and if you want to compress, you can copy a rar.exe:

if ($ARGC!= 2 | | in_array ($ARGV [1], Array (' –help ', '-? ')) {
?>
Backup Ver 0.01, for Win95/win98/winnt/win2000/winxp on I32

PHP Shell script for the backup MySQL database.

Usage:

Can is database name you would like to backup.
With The–help, or-? Options, you can get this help and exit.
} else {
$dbname = $argv [1];
$dump _tool = "C://mysql//bin//mysqldump";
$rar _tool = "D://php4//rar";
@exec ("$dump _tool–opt-u user-ppassword $dbname >/$dbname. sql");
@exec ("$rar _tool a-ag_yyyy_mm_dd_hh_mm $dbname. rar $dbname. sql");
@unlink ("$dbname. sql");
echo "Backup complete!";
}
?>

Add a task schedule and enter the command in this step (shown in Figure 2):

D:/php4/php.exe-q d:/php4/backup.php DatabaseName

The time is set to run once a day and then run this task.  Finally, a RAR file consisting of database name and current time is generated in the d:/php4/directory. Congratulations to you! It's done!

Of course there are many ways to backup, readers can do according to their favorite to do!

The above is the original. Combined with my real cheap, the supplementary note is as follows:

If an error occurs:

An error occurred while trying to set up task account information
The specified error is:
0x80070005: Access Denied
You do not have permission to run the requested operation

On the top ' 4. The system will then require the user to set the appropriate username and password, so that the system can automatically run in the future. It is best to use the "system" user and the password may be blank.
This system has a very high privilege, higher than your administrator, so you should not do anything when you run the command, this is not an unconditional implementation of any hint, this permission under you kill the core process is OK.

2, add a task plan, enter the command in this step:

D:/php4/php.exe-q d:/php100/test.php

The correct form should be

"D:/php4/php.exe"-Q "d:/php100/test.php"

That is, the path should be enclosed in double quotes.
